T1 - Evacuation dynamics under consideration of vulnerable pedestrian groups N2 - The understanding of human behavior during evacuation processes is an important matter to improve the safety of infrastructures. In many countries, the implementation of performance based codes enables fire safety engineers to use computer based calculation tools to predict and evaluate pedestrian movement and human behavior in buildings. The models are based on experimentally obtained parameters and theoretical models. Pedestrian behavior can be influenced by the characteristics of the buildings (e.g. type of the building) as well as the characteristics of individuals and the pedestrian group. This paper shows that the approach of Required Safe Egress Time (RSET) / Available Safe Egress Time (ASET) is imprecise with regard on heterogeneous pedestrian groups, because this concept completely neglected the variability’s in individual pre-movement and movement abilities.

Comparisons of the results of such studies require to distinguish carefully between homoge neous and heterogeneous populations. A series of well-controlled laboratory studies were performed with participants with and without impairments. Individual pedestrian movement through a corridor and a bottleneck of all participants was recorded by wide-angle HD-cameras and the trajectories of each participant was extracted automatically by using PeTrack. This contribution shows that considering participants with impairments in laboratory studies of pedestrian movement is feasible and reports preliminary the inuences of movement. Preliminary analyses imply two main conclusions and a preliminary forecast: _rst, social behaviour in laboratory studies is considerately and respectful; we did not observe altruistic behaviour; but considerately behaviour may encourage a reduced capacity at bottlenecks. Second, technical devices to improve movement require space and reduce capacity.

Since the safety characteristics of dusts and gases are determined under different conditions, there has been considerable confusion about the influence of flammable gas on the (dp/dt) of dusts and vice versa. While some investigations showed comparably higher values for hybrid mixtures, others stated that the highest value for the gas component alone is the worst case. The first part of this paper focuses on the confusion around the different statements about (dp/dt)𝑚𝑎𝑥 of hybrid mixtures and where they come from. In the second part of this paper experimental results are presented that illustrate how to clarify the different findings of past research and show what to expect as a real worst-case-value for hybrid mixtures.

Bottlenecks are of special interest because of their importance for egress routes and as they result in a reduced capacity. The empirical relations as the density-dependent movement speed or flow rate were derived by studies under laboratory conditions, which were usually conducted with populations of homogeneous characteristics forbetter control of influencing variables. If individual characteristics of a crowd become more heterogeneous, individuals were forced to adapt their individual movement and control individual manoeuvring. These unintended interactions lead to a different shape of the fundamental empirical relations. Here, we present results from a movement study under well-controlled boundary conditions in which participants with and without different characteristics of disabilities participated. To consider the effect of different heterogeneities on the capacity of a facility, fundamental diagrams are generated using the Voronoi method. If participants with visible disabilities (such as using assistive devices) are part of a crowd, significant differences relating to the shape of the empirical Relations and the capacities are found. This indicates that the heterogeneity of a Population leads to an increased interpersonal interaction which results in influenced movement characteristics.

The understanding of interactions and influencing factors in heterogeneous groups on key performance figures is fundamental for a safe design. This contribution presents results of experimental studies on movement of a crowd through a bottleneck involving participants with and without disabilities. High precise trajectories of the attendees extracted from video recordings were used to calculate density and velocity of the participants. Besides the well-established fundamental diagram new insights into the individual relation between density and velocity are discussed. A complex structure and considerate behaviour in movement implicates a strong influence of the heterogeneity on key performance values of safe movement.

A1 - Hofmann-Böllinghaus, Anja T1 - A score regarding the need for assistance - considering pedestrians with impairments in evacuation planning N2 - The capabilities of pedestrians for evacuation have a significant impact on the time required to reach a safe place. Usually, the evacuation is split into two main stages: pre-movement-phase and movement-phase. For both a large number of studies investigate different representations of behaviour and impacts. But the influence of impairments is usually not taken into account. In addition, most of the scientific researches focus the investigation of the movement phase. This publication presents a novel approach to score the need for assistance and to estimate the effect on evacuation performance. The proposed score considers characteristic impairments in three dimensions of behaviour: reception, perception and realisation. In an unannounced evacuation training in a sheltered workshop, the evacuation behaviour and pre-movement phase were analysed. The analysis indicates that the pre-movement time depends on the kind of impairment as well as on organisational boundaries. Despite the special needs for assistance, the evacuation process in a sheltered workshop is quite similar to other sub-populations. T2 - 5.

This study compares the reliability of three simulation tools and the calculation method by Predtetschenski und Milinski with a controlled evacuation exercise of a lecturer room. The comparison shows that each simulation tool used underestimate the total evacuation time and that an indicator for a low level of fitness does not necessarily lead to a long evacuation time. Results revealed that calibration of simulation tools is required to model heterogeneous population properly. Therefore, further experiments with a realistic, heterogeneous composition of participants have to be made.

These data are typically based to young and fit populations. However, the movement abilities of occupants who might be involved in evacuations are becoming more variable—with the building populations of today typically including increasing numbers of individuals: with impairments or who are otherwise elderly or generally less mobile. Thus, there will be an increasing proportion of building occupants with reduced ability to egress. For safe evacuation, there is therefore a need to provide valid Engineering egress data considering pedestrians with disabilities. Gwynne and Boyce recently compiled a series of data sets related to the evacuation process to support practitioner activities in the chapter Engineering Data in the SFPE Handbook of Fire Protection Engineering. This paper supplements these data sets by providing information on and presenting data obtained from additional research related to the premovement and horizontal movement of participants with physical-, cognitive-, or age-related disabilities. The aim is to provide an overview of currently available data sets related to, and key factors affecting the egress performance of, mixed ability populations which could be used to guide fire safety engineering decisions in the context of building design.

In response and to reduce this lack of data a series of well-controlled large-scale movement studies considering pedestrians using different types of wheelchairs was carried out. As a result it is shown that the empirical relations are strongly affected by the presence of participants with visible disabilities (such as wheelchair users). We observed an adaption of the overall movement speeds to the movement speeds of participants using a wheelchair, even for low densities and free flow scenarios. Flow and movement speed are in a complex relation and do not depend on density only. In our studies, the concept of specific flow fits for the nondisabled subpopulation but it is not valid for scenario considering wheelchair users in the population.

The understanding of interactions and influencing factors in heterogeneous groups on key performance figures is fundamental for a safe design. This contribution presents results of experimental studies on movement of a crowd through a bottleneck involving participants with and without disabilities. High precise trajectories of the attendees extracted from video recordings were used to calculate density and velocity of the participants. Besides the well-established fundamental diagram new insights into the individual relation between density and velocity are discussed. A complex structure and considerate behaviour in movement implicates a strong influence of the heterogeneity on key performance values of safe movement.

A1 - Hofmann-Böllinghaus, Anja T1 - The influence of individual impairments on crowd dynamics N2 - Emergency exits as bottlenecks in escape routes are important for designing traffic facilities. Especially the fundamental diagram is a crucial performance criterion for assessment of pedestrians' safety in facilities and an important basis for calculation methods. For this reason, several studies were performed during the last decades which focus on the quantification of movement through bottlenecks. These studies were usually conducted with populations of homogeneous characteristics to reduce influencing variables and for reasons of practicability. Studies which consider heterogeneous characteristics in performance parameters are rarely available. In response and to reduce this lack of data a series of well-controlled large-scale movement studies considering pedestrians with different disabilities was carried out.
